Encapsulation and Vapor Barriers

What is an acceptable moisture reading in a hardwood floor?

An acceptable moisture reading in a hardwood floor depends on various factors, including the species of wood, the environment, and the National Wood Flooring Association (NWFA) industry standards. Typically, moisture content between 6% and 9% is considered acceptable for hardwood flooring installed in most climates.

Encapsulation:
Encapsulation involves applying a moisture barrier to the subfloor to prevent moisture from rising from the ground into the hardwood flooring. These barriers can be installed under the flooring or on top of the subfloor.

Vapor Barriers:
Vapor barriers are moisture-resistant sheets installed on top of the subfloor to prevent excess moisture from the air from reaching the hardwood flooring. They are particularly beneficial in areas with high humidity or moisture levels.

Acceptable Moisture Readings:
The NWFA recommends the following acceptable moisture readings for hardwood flooring:

  • Prefinished solid hardwood: 6% to 9%
  • Unfinished solid hardwood: 6% to 8%
  • Engineered hardwood: 6% to 8%

It is important to note that these are general guidelines and actual moisture readings may vary slightly depending on the specific conditions. To ensure optimal performance and prevent damage, it is advisable to consult with a qualified flooring professional for accurate moisture testing and recommendations.
